BRADY, AND ALBERT B. BRADY, OF

WATER-MOTO R.

SPECIFICATION forming part of Letters Patent No. 410,132, dated August 2'7, 1889.

Application filed May 2, 1889. Serial No. 309,384:- (No model.)

. a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Water-Wheels, and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to water-wheels; and it consists in the novel construction and combination of the parts hereinafter fully described and claim ed, whereby the water-wheel is adapted to work when submerged in the current of a running stream, and may be moved about as found convenient.

In the drawings, Figure 1 is a plan view of the machine from above; and Fig. 2 is a crosssection through the same, taken on the line 00 a: in Fig. 1.

The frame of themachine consists of two side plates A A, securely connected together and provided with the inclined water-guide plate B. j

The water-Wheel is provided with two end disks 0, connected together by the cylindrical barrel D. The water-wheel is secured upon a shaft d, journaled in the side plates A A.

E is a curved plate providedwith the longitudinal flange e,adapted to rest upon the guideplate B, and F are end flanges which are journaled on the central shaft d of the water-Wheel.

E are curved toothed racks secured to the ends of the curved plate E, and F is a shaft provided with a cranked handle f or other equivalent means for revolving it in its bearings in the side plates A A.

G are toothed pinions secured upon the said shaft F, which gear into the curved toothed racks E.

H are curved arms pivoted to-the disks 0 near their periphery by means of pins or rods 72.. These arms may be straight; but curved arms are preferred, as they hold the water bet ter. The free ends of the said arms are free to oscillate between the cylindrical barrel D port.

course and anchored to the river-bed or" secured to piles or to any other suitable sup- The arrows in the drawings show the direction of the current. When the curved plate is closed, as shown, the wheel is not revolved by the water. The wheel is started by turning the shaft F and opening the curved cover. The dotted lines in the drawings show the position of the cover when open to its widest extent. The water rushes up the inclined guide-plate and through the opening between the top of the said guide-plate and v the flange e of the curved plate E. The flange e causes the water to be deflected, so that a greater volume of it is obliged to pass through the machine. Thewater strikes against the arms H at the top of the wheel and revolves it in the direction of the arrow. When the arms approach the under side of the wheel,

they are turned upon their pivots by the weak;

water-current passing under the Wheel and they fall against the stops 7L, thereby ofierin g very slight resistance to the revolution of the wheel. justed by turning the shaft F to vary the position of the curved plate and cause more or less water to act upon the wheel, as desired.

The speed of the wheel may be ada y The wheel is revolvedby the upper current of water, which is swifter and more powerful than the water running next the river-bed and in frictional contact therewith.

The'power may be conveyed to the shore by means of a shaft, preferably coupled to the water-wheel shaft by a universal joint of approved construction, and a number of similar water-Wheels may be used, if desired, and have all their shafts coupled by universal joints, so

that it-will not be necessary to place them eX- actly in line on the river-bed.

WVhat I claim is l 1. The combination, with the two side plates andthe inclined water-guide plate secured be tween them, of the water-wheel journaled in the side plates substantially in line with the top of the guide plate, and the adjustable curved plate provided with flanges at each end having their extremities j ournaled on the Water=wheel shaft, and a longitudinal flange resting on the upper end of the said guidcsaid guide-plate, and a toothed rack, and a plate, substantially as and for the purpose set revoluble toothed pinion gearing into the said forth. rack for adjusting the position of the said 2. The combination, with the two side plates curved plate, substantially as and for the pur- 1 5 5 and the inclined Water-guide plate secured pose set forthbetween them, of the water-wheel provided In testimony whereof Iaffix my signature in with a shaft and journaled in the side plates presence of two Witnesses.

substantiallyin line with the top of the guide- LOREN R. XYITHERELL. plate, the curved plate provided with end Vitnesses:
